As in all other regions, SWAPO was by far the strongest political party since Namibian independence. In February 2009, then-governor Hanse-Himarwa was condemned by the National Society for Human Rights of Namibia for declaring Hardap Region "SWAPO territory" and urging supporters not to allow other political parties to "invade" the region.

In the 2004 presidential election, the region supported Hifikepunye Pohamba of SWAPO with a narrow absolute majority of the votes (52%), following by Ben Ulenga of Congress of Democrats (21%) and Katuutire Kaura of the Democratic Turnhalle Alliance (16%). Four other candidates combined for the 11%.

In the 2004 regional election for the National Assembly of Namibia, SWAPO won all six constituencies.

In the 2015 regional elections SWAPO obtained 65% of the total votes (2010: 60%) and won seven of the eight constituencies with only Rehoboth Urban West narrowly won by the opposition. In the 2020 regional election the Landless People's Movement (LPM, an opposition party formed in 2016) was the strongest party. It obtained 45% of votes overall and won seven of the eight constituencies.
